Application filediebruary'; e, 1923'. swarm. swam! This inventionrelates toydispensing de vices, and. more particular-Ly to that classof. dispensing devices comprising a: cartridge-- container or refillfor: the dispensed material. and; a casing into which thecartridge dej-rtachahly fits.

One object ofthe invention is to provide a dispensing device of thistype in' wliichi the; operationsof inserting and removing the cartridgein and from the casing: are IB-' 'duced to the extreme of simplicity.

Another object is to provide a device of the type stated inwhich theconstruction of the casing is greatly simplified, involving no partscoming in contact with the dispensed material.

A further object .of th-e' invention isv to provide means fordetermining thezamount. of the materialremaining at any time: in the:cartridge. i

A still further object) isv to provide the cartridge with: a. vaivecontrolling the dis:- oharge opening and automatically operative whenthefeedingv mechanism is: operatedto uncover-the opening; intermittently'to per mit the discharge of' predetermined limited quantities of thecontainedmaterial;v

Another object. is; to provide: means for preventing caking' of thematerial" in. the

cartridge; around the discharge opening A further object of the:invention/is to provide a novel cartridge: oryrefilltwhiclv' comprisesin itself the mechanism inciuding a plunger, for discharging containedimate riaL I A further. object is to providemeans' for indicating theposition. of theplnnger in the' cartrid'g Another object is to providemeans for" automatically disconnecting the plunger from; the feedmechanism: when the; lunger reaches the discharge end of the: cartridgewhereby further manipulation of: the feed mechanism. has no: effect uponthe plunger.

It is further contemplated-to provide a.

casing'for the cartridgewhich is practically waterproof whereby thedevice, when used in connection with shaving] brushes and the.

like, is not: subjiectto: the passage of: water into the interior of thecasing and into the cartridge. 3 l

The mechanism by means o-fi which. these and other objectsappearingjhereinafter are accomplished is illustrated in' the attached:

The cartridge I has in':' one end. a discharge openlng 3, theucartrldgeat this endaini the present instance .being drawn out intoan elongated.reduced: nozzle 4,. in the end of i which the said. opening." 31-i'slocated-L. This drawn-out end portion also includres. at the base oftltenozzrled a .polygonai formation. 7

5, thepnrpose of which Xvi-lithe hereinafterdescribecl.

In the opposite end of th'etcartridge is seecured: a-fixejd; end:plated, this: plate in: the f present instanceibem gi confined inlthe:barrel ofthe cartridge by beading. orspinningt over the edge ofthebarrel; as indicated at The plate 6=has a central circular: aperture,

'8 through which projects a rectangular stem 9, the; stem extending the.lengthiofthe car'- trid-ge on: the: inside, rounded end norm-allyclosing the discharge opening 3. The: stemisconfined within the"cartridgeby means, in the present instance,

of a: pin 10 which passes through the stem inside: of the plate 6, andhaarsagainst' the top of thedished-spring 11 whoseedges bear" againstthe inside of the v and having its upper" said plate- 6 Aspreviouslystated, the end of the stem 9 pro- ,jects through the circularopening 8 in the plate 6, and secured tothis projecting end is a disk orplate 12 which normally lies against the under side of theplate ti asshownin Fig. 1.

i The plate 12 is provided with four semicircular protrusions 13arranged in a circle concentric with the plate and separated in thepresent instance by90 angles, these protrusions being adaptedzto occupyfour similarly arranged recesses 14 in the under side i of the fixed.plate 6, as illustrated. in Fig. 1. 1 These projections or knobs 13 whenthe plate 12 is rotated ride out of these recesses and thereby forcetheplate 12 outwardly away from the plate 6, the plate 12 carrying withit in this movement the steni9 to which it is attached. The plate 12hasalso in the present instance a series of apertures 15, 15, which areformed by pressing out segments of the metal of this plate so that thesepressed-out portions of metal 16 project outwardly at right-angles fromthe disk 12,- as

shown in Fig-s1 and 3, thereby forming wings which provide contact orameans for grippingthe plate 12 for turning it.

Located in the interior of the cartridge 1 and having a centralrectangular opening through which; the stem 9 extends is a piston orplungerl'l', cylindrical in form and having its periphery threaded tocorrespond with thein terior' threads of the'cartridge, 1 With thearrangement as described and il lustratedin'Fig. 1, it will be apparentthat rotation of the stem 9 eifects a longitudinal movement of theplunger 17 in the cartridge 7 due to the co-action between'the threadson the plunger and in the barrel of the cartridge.

It will further be noted that the fixed plate 6 is apertured'at 18,these apertures corre sponding substantially with the apertures 15 I inthe plate 12? and registering.- with these latter openings when theplate 12 is in the normal {position shown in Fig. 1.:

Sincethe spring 11, as shown in Fig. 3, is substantially cross-shaped,these openings 15 and 18- provide a means for ascer-- taining theposition of the plunger17 in the cartridgeand the amount of thecontained material which has been discharged from the cartridge.

' The-stemQ is grooved near the top, as

indicated at 9, this groove being so positioned that whenthe plungerreachesthe topyof the cartridge, it passes oii intothis groove and soloses operative contact with the stem. As a consequence, furtherrotationfof thestem; has no effect upon, the

. plunger, thus preventing possible jamming andinjury to the workingparts of the easing hereinafter described. It will also be noted thatthe upper end of .the' stem fits neatly the-interior of the, nozzle 4, ascourrule 22. containing bristles 23 which constitute a brush. In thepresent instance, the end of the casing'20 is somewhat reduced andthreaded a's indicated at 24,'the ferrule 22 also being providedwithinternal threads correspondingto the threads on theicasing'. As clearlyillustrated, the ferrule is centrally' apertured, the nozzle 1projecting through the aperture into the base of the bristles 5 V V Thecasing 20, which is cylindrical in form, has at its other end a cover.or cap I comprising in the present instance a member 25 of the usual capformation, inwhich- 1s rotatively secured a sleeve 26, the sleeve beingsecured in the present instance by means of spinning the upper edge 27into an annular recess 28 in the sleeve. The sleeve 26,

as best shown in Fig. 5, is provided with angular slots 29 which with acorresponding number of pins or projections 30 on the inside of thecasing 20 form a bayonet joint, by means of which the sleeve and itsassociated member 25 are attached to the casing.

It will be apparent that the member 25 is Iv freely'rotatable withrespect to the sleeve 26,'and thismember' is provided in the" in teriorthereof with a plurality of pins or projections3l which are adapted toengage the flanges or wings 16 projecting, as previously described,outwardly. from the plate 12 whereby'when the member 25 is rotated,

it carries with it the said plate 12'and the stem 9 tO WhiCh thelatteris attael'iedThe T llU sleeve 26, as shown in Figs. 1 and 5, is providedwith a suitable seat 82 for'the lower i) Ii llli) edges'ofthe barrel ofthe casing 20, and that 6 portion of the sleeve 26 immediately below theseat extends to form a grip 1 whereby this sleeve may be rotated ifdesired independ'ently of the member 25,- the periphery of thisprojecting portionof the sleeve being knurledto provide a suitable grip,as also .is the periphery of the member 25.

As shown' 'n Figs. 1 and, 2, the caslng 20 is provided in the dischargeend with a plate or dislr33 having a polygonal opening 34-:corresponding to the polygonal form ofthe portion 5 of the cartridge,this-por-- "tion 5, when the cartridge is in place in the casing, lyingwithin this aperture 34 in the plate whereby the cartridge is prevented.from rotating in the casing.

Coincident withthe uncovering of this discharge-opening 3,theplunger 17 is advanced; in the cartridge, with the, result that, a.portion, of the contents of the cartrige is expelled; through thedischarge, port... l/Vith' the arrangement illustrated and described,each quarter rotation of the.

It will further be apparent that numerousmodifications in the arrangement of parts and details of constructionmay be made with no departure from the essential features of theinvention.

In the modification of Figs. 6 to 11, we have illustrated a form of ourdevice in which the spring 11 has been eliminated. In this instance, amember 40, corresponding to the plate 12 in Fig. 1 to which the stem 9is secured, functions as the resilient means for retaining the stem inthe normal aperture-closing position. As clearly shown in Figs. 6 and11, the lower edge of the cartridge is beaded inwardly over thedownturned flanged edge of a fixed plate 41, this beaded-over portion 42of the shell preventing outward movement of the outer edges of theplate-40. In this instance also the plate 40 is apertured for thereception of pins 43, 43, on the member 25 of the casing'cap, so thatwhen the latter is r0- quantity; of the.

As the 7 plate. 4.0! is rotated,projections 434:, 44:, there-i onv pass out otlthe. apertures providedyforv them in the fixed plate 4;:1, therebytfiexing; the plate-a0outwardly at the center and drawing downwardly the stem 9 so that theport-3is uncovered. Inthis instance also, there is provided meansforindicating the positioned" theplunger in the cartridge, the indicator:consisting of a rider adapted: totravel in aislot. at in. oneofathearins/ot' the memberAO, this rider. which: is best and. astheplunger is fed upwardly in the towards the center of the member 40, the.
